Depth of field is the amount of distance between the nearest and furthest objects that appear in acceptably sharp focus as seen by a camera lens. This field varies with the focal length of the lens, its f-stop setting, and the object distance from the camera.

DOF PRO features various modes to suit virtually any requirement. In its most powerful mode, DOF PRO uses a specified depth map to derive an accurate depth of field effect. A depth map is a greyscale image where the grey level at any given point represents the distance of the object from the camera at the same point in the original image. Most 3D computer graphics applications are easily capable of producing depth maps along with the rendered image. For photographic images, the user can create the depth map manually which can be greatly facilitated through the use of the filter’s powerful built-in gradient features.
